' rwIs'rmG-Macnmn' To all whom it may'concer'n: I Be it known that 1, WILLIAM SCHOLES, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Twisting-Machines, whereof the following :is a specification, reference being: had to the accompanying drawings. :.--The Invention relates to machines com- "monly -..tw1sters, whereby yarns orlpaper' ribbons known in the textile trade as are twisted into twine 1n preparation for weaving. f 1- -The'present improvement. is .not only -rected to. means forsimultaneously winding the twisted maspools, ;ferred terial intocops, so as to be'in the proper form for use in the shuttles of looms, etc.

Heretofore, it has been customary to perform the twisting upon one machine, where by .the twisted twines were wound upon and the latter subsequently trans toanother machine commonly termed a cop winder]? ,A further object of the present invention is to provide'a construction whereby there is produced a relative therethrough by the'receiving spindle,so as means..'

to give the material a very tight twist. before it' -is' crushed and attenuated by the crushing According these two functlons, thereby obviating the hen'ds a novel 'PIO(111Cil1g the twisting, which mechanism, is so coordinated with devices for cop wind-V I ing that both may be automatically rendered necessity for the two separate stages above noted, and effecting a decided decrease in thecost of manufacture.

The present improvement also compreand simplified mechanism for inactive upon the completion of a cop.

In the accompanying drawings, Figure I, is a vtransverse sectional view of .a machine conveniently embod ingmy invention.

. The machine'emb'odying my-improvements' the supporting frame 10, of the machine,

and-is adapted toreceive the squared portion 11, of the spindle; By this arrangement positive rotation is impartedto the-spindle while the latter may at'the. same time shift longitudinally as the material accumulates:

thereon in the formation of: a;cop.

Cooperating with the spindle, is a winding e umrEosTArEs EENTOFFICEQ cone: 12, mounted in the end of a bifurcated arm 13. Said arm islooselyfulcrumed about a rod 15, fixed in theframeof'the machine,-

and a spring 16, serves to keep the winding cone in proper operative position with relation to the spindle 6, and is further functional in allowing the arm 13, to be sufficiently withdrawn by the operator to permit theremoval of a'completed cop. As the material builds on, the spindle, the winding cone is instrumental: in causing the spindle to be shifted inwardly until'the collar 17, thereon engages the trip 18, which controls the shifting of thefbelt 2, fromthe tight pulley 3,

' on the. sleeve 5,to the loose pulley 19', directly ad acent. The trip 18, is freely 'fulorumed abouta fixed supporting rod 20, and in the position shown in Fig. I, arrests the collar 21, on the shifter rod 22, and locks the'latter against the pressure of the spring 23, which shift the belt 2, to the loose normally tends to pulley 19,'the eXtentofshifting being determined by a buffer collar 25. The shifter rod 22, terminates in a hand knob 26, whereby theparts maybe manually restored to driving position beginning a new cop. Y

A feeding device is'also operatively asso-i mated with the-spindle and-winding clone.

"This, device is in the form of an oscillating lever 27, the amplitude of its oscillation c0r-- responding in extent to the length of the cone. rod 15, already described and is maintained,

:by, means of a spring 28, in engagement with a cam 29, mounted upon a longitudinal shaft 30, which .is driven by a belt 31, from the main'shaftl.

gravity, in frictional contact with a disk 36.

This disk is rotatively supported in the transverse portion 37, of the frame of the machine, andis integrally formed with a sheave 38, which is also driven from the main shaft 1, by a belt 39.

is f preferably rotated in a direction "corresponding with the I natural curl of the paper occasioned by beingunwound from the center of the roll.

mounted'upon a suitable supporting stem 42,

j the ribbon is 'directedthrough afiseriesof stationary crushing and. attenuating eyelets 45, 46,:and 47, preparatory to being wound upon the spindle in the formation" of the cop.

7 "As best shownin lFigs. II,.and I I' I, these eyeis also to'be noted'that the bore of the eye-- 'letsare supported in arms 48,- Which are vertically adjustableupon the stem 42. It

lets is successively decreased so that a gradu'al crushing and attenuation is effected, while the twisted ribbon is drawn by virtue ofthe rotation of the spindle. i I

It will'also be seen that because of the relative twisting movement between the roll and the crushing eyelets, which movement is givenin the direction of the natural unwinding of the ribbon from "the roll, there is effected a very-tight wrapping of the ribbon beforeit reaches the eyelets where it is given rmanent set as it passes therethrough.

a e l vhile I have shown three eyelets in the illustrations, it is of-course to-Ibe understood that I do not wishto be thus limited, since this numberga'nd the successive gaging, may

be varied, not only'inaccordance with thewidth'of the ribbon, but also'with the kind of materialto be twisted. w 7 'Theam'ple length'of the strandof paper ribbon constantly maintained between the guide roll 40, andthe supportingtable 33,

-. is such asto permit an automatic compensation between the successive convolutions of. the spiral created-through the rotations of fitheSaid table, whereby a twist of substanchangin the speed ratios between the rota- "tially even pitch is effected before the crushing is accomplished. The pitch of thetwist may obviously 'be' .varied indefinitely by ion'of t e supporting table 33,for the roll of material, andthat ofthe winding spindle.

Inorderthat the supporting table may be )simultaneously' stopped with the winding spindle at the completion of a cop, I have I provideda brake which is automaticallyopera'ted in conjunction with the shifting mec anism'for the belt 2. The saidbrake-is in the with the periphery'of the table 33. other-armof bell-;cr ank 50, is coupled by After passing: over the guide rolls 40, and '41,

having a finger 56, which is normally engaged by a'pin 57,- on the shifter rod 22, to

releasethe brake'in opposition to the pull of In operation, thelongitudinal motion of the shifter rod causes the release of the lever 55, so that the brake is automatically applied through the instrumentality of spring 58, to

prevent further rotation of'the table simultaneously with the shifting of the: belt 2, to

the idle pulley 19, in rendering the winding spindle inactive. Thereupon, the. operator may remove the completed cop, draw the spindle forward as far as'allowed byiit'siterminal collar '60, and reset the belt-shifter:

and the parts controlled thereby, the hand knob 26. The machinewill then be in condition for beginning a newcop.

While I haveshown the organization herein described: as confined to-the windingof a that thesame may be compounded'indefi- V by meansof-J single cop, it is ofcourse to be understood nitelyin a machine for producing multiple windings, without deviating from the :scope of my invention.
